Description:

Abstract:

The United States Geological Survey (USGS) is conducting a study on the effects of climate change on ocean acidification within the Gulf of Mexico; dealing specifically with the effect of ocean acidification on marine organisms and habitats. To investigate this, the USGS participated in cruises in the West Florida Shelf and northern Gulf of Mexico regions aboard the R/V Weatherbird II, a ship of opportunity lead by Dr. Kendra Daly, of the University of South Florida (USF). This cruise occurred January 3-7, 2011, leaving from and returned to Saint Petersburg, Florida. The USGS collected data pertaining to pH, dissolved inorganic carbon (DIC), and total alkalinity in discrete samples. Thirty-six underway discrete samples in January were collected approximately hourly over a span of 745.3 km Flow-through conductivity-temperature-depth (CTD) data were collected, which includes temperature, salinity, and pH. Corroborating the USGS data are the vertical CTD profiles collected by USF, using the following sensors: CTD, oxygen, chlorophyll fluorescence, optical backscatter, and transmissometer. Additionally, discrete depth samples for nutrients, chlorophyll, and particulate organic carbon/nitrogen were collected.

Purpose:

The purpose is to study the effects of climate change on ocean acidification within the Gulf of Mexico.

Supplemental_Information:

The USGS Saint Petersburg Coastal and Marine Science Center (SPCMSC) - St. Petersburg, FL, assigns a unique identifier to each cruise or field activity. For example, 11CEV01 tells us the data were collected in 2011 for the Climate and Environmental Variability and the data were collected during the first field activity for that project in that calendar year. Refer to http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html for a detailed description of the method used to assign the cruise ID.

Overview_Description:

Entity_and_Attribute_Overview:

All attributes are common between the three data formats provided (.csv, .xls, .shp), except for the attributes FID and SHAPE (indicated by *), which are found only within the shapefile (.shp) because they are unique to that data type. Additionally, the GPS data was taken from the Weatherbird II's navigation logs and was matched with the time logs on the sonde. These data have not been QA/QC yet, and as such could have data errors due to tubes clogging, or flowthrough shutdown for inclement weather.
